Customer Speaks

 

 





'It’s indeed a proud moment to inform you all that Dhvani Research is now officially certified to check the macroscopic degree of purity of bar material according to DBL 4019 and SEP 1927 by Daimler Germany. Steel cleanliness evaluation using ultrasonic immersion testing has become an industrial standard to evaluate steel mills and suppliers. Continuous evaluation of steel with an international standard helps suppliers raise the quality bar and hence the revenue by offering quality products. Dhvani was able to produce identical test results on a sample already inspected at Germany using our in house built software and scanner. The sample was inspected using the acqUT series software on a SHRUTI -6S machine with a 10Mhz transducer. SHRUTI series machines has proved it’s mettle by providing comparable results with machines extensively used by research labs globally. Dhvani is proud to announce that we are the officially approved Indian lab of Daimler to assess macroscopic degree of purity of steel casts from Indian steel market. '

Thank you very much for your kind services and support for conducing C-scanning examination on the spot welded samples (12-Nos) of continuously annealed advanced high strength steels. The non-destructive analysis using C-scanning of the spot weld nuggets, manifested reasonable correlation with the results that we obtained after analyzing the nuggets by destructive metallographic examination. This was our first venture to examine the nuggets of spot welded samples using C-scanning technique,which was quite satisfactory. We believe this method will help us to build more confidence in using the technique extensively for such examinations and we look forward to your continues help, support and services.

We are pleased to inform you that the Integrated automated ultrasonic transducer characterization and Immersion C-scan imaging system supplied by you is working well and giving us extremely good results. We are happy to get a system which is as per ASTM E 1065-08 standards, which is required to meet our quality requirements.

The results obtained on composite test laminates are extremely good , we have extended the system for measuring velocity and attenuation very accurately. The system is also capable of performing immersion guided wave experiments which are being planned now. The advanced software for transducer characterization provided by you is unique as it has capability to provide us all the required data about the transducer being tested. This is extremely important for our quantitative measurements.We request you to provide your continued support as and when required.
